burn mark / hole effect with configurable dimming 'ember glow'

existing input method for the Lightning effect could work (plotting points to draw the path of the scorch mark) with controllable thickness although would also be good to be able to draw a re sizable ellipse for laser blasts / bullet holes (an ellipse would allow altering the 3D perspective between key frames)

even better still would be the ability to draw a 3D plane and allow the scorch marks / hole to be placed relative to that plane, so that e.g. you could draw a 3D plane matching the perspective of a wall, floor or other object and move it through the key frames to match the reference object in the video (automatically animating the perspective of the effect relative to the plane)
